Time course of the development of mechanically-evoked behaviours after injury of the
mental nerve. 50% withdrawal thresholds evoked by graded stimulation of the chin hairy skin with
von Frey monofilaments after chronic constriction injury (CCI; A), partial tight ligation (PTL; B) and sham operation (C) of the mental nerve. The operation was performed on day 0 (indicated by the dashed
line). Symbols are mean ± 1 S.E.M.
